JOURNAL-LUBRICATING DEVICE.

Specification of Letters Patent.

Application filed November 16, 1918. Serial No. 262,883.

To all whom it may concern:

Be it known that we, IRA S. DOWNING and EDWIN S. PEARCE, both citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Journal-Lubricating Devices, of which the following is a full, clear, and exact specification, taken in conjunction with the accompanying drawings, forming a part thereof.

Our present invention. relates to lubricating devices for car-axles and is in the nature of an improvement in the invention described in our co-pending application for Letters Patent of the United States, Serial Number 236,282, one object of the improvement being to cheapen and simplify the device and to increase the efficiency and utility of the same. The invention also contemplates the provision of certain novel details of construction, combinations and arrangement of parts of the improved device, where'- by certain important advantages are attained, as will be more fully described hereinafter, and pointed out in the claims.

These objects and advantages we attain by means of a constructionillustrated in preferred form in the accompanying drawings, wherein Figure 1 represents a vertical sectional view of a journal box embodying my improved device;

Fig. 2 is a horizontal sectional view thereof taken on the line 22 of Fig. 1;

Fig. 3 representsa view in front elevation of. the journal cam and the roller in the vibratory plate with which the cam cooperates; and

Fig. 4 is an enlarged detail view of one of the oil-projecting nozzles carried by the vibratory plate.

Referring to the drawings, the reference character 5 designates the journal boX, 6 the journal or car-axle, 7 the customary bearing or brass for the journal, and 8 denotes the oil chamber in the basal portion 9 of the boX in which is stored the oil designed to be projected upwardly toward and on the journal by the nozzles of the vibratory plate 10 in order to lubricate the bearing surfaces between the journal and its brass. Heretofore, waste or packing saturated with the lubricant has been depended upon to lubricate these surfaces, but this has been found to be wasteful as a considerable portion of the oil absorbed in the waste'was not fully utilized as a. lubricant upon the surfaces requiring it, and furthermore, necessitated the employment of different grades of lubricant for winter and summer use.

Our invention is designed to eliminate these disadvantages, and to provide a very efficient and simplified device capable of attaining, with a minimum amount of oil, the effectual lubrication of such surfaces by the oil under any and all conditions of service.

In carrying'out our invention, the plate, 10 is hingedly mounted in the chamber at its rear end by means of a hinge-pin 11,'and extends forwardly and centrally beneath the journal and over a series of alined oil pockets 12 to have its front end yieldingly supported by means of a compression spring 13. This spring is centered by the bosses 1 1 and 15 which terminally engage its ends, the boss 15 being formed integrally with and extending upwardly from the base of a front recess or pocket 16 which isdisposed in advance of the oil pockets 12. These pockets are depressions formed in the base or lower wall 17 of the'box to receive the oil intended to be projected upwardly through the nozzles 18 during the vibration of theplate which carries them.

The forward end portion 10 of the plate or nozzle carrier 10 is positioned'intermediate a pair of guide wings 19 designed to I maintain it against side-sway orundue lateral movement, and just back of this portion 10 is an enlarged portion 10 slotted at 20 to receive a friction roll-er 21 whose hubs have bearings at 21" in the plate, and which frictionally engages the cam 22 fixedly mounted upon the front face of the journal. Obviously, as the journal rotates the plate vibrates under the cooperative in- Patented Nov. 29, 1921.

fluence of the cam and roller on one side thereof and the co-active compression spring on the other. The cam determines the amplitude of this vibratory movement, and being in a constantcontactual relation with the roller no positive limiting member is re quired for the nozzle plate.

As illustrated perhaps more clearly in Fig. 4;, it willbe seen'that the nozzle 18 has a flared or conoidal intake 23 and a contracted exteriorly threaded neck portion 24. provided interiorly with a. narrow passage 25 communicating with the intake and lead ing to an outlet 26. This outlet is so construt-ted as to confer upon it a higher velocity of discharge than intake, the kinetic energy being employed, as will be understood, to carry the oil jet to the journal as the plate vibrates. The nozzle is further formed with an annular flange or shoulder 27 designed to take against the lower face of the plate when the neck has been inserted through the aperture therein provided for it, and is maintained in position by means of a nut 28 adapted to be screwed down on the trireaded neck.

i hen thus positioned, each of the nozzles has its flared intake 23 orojecting toward and penetrating slightly into its corresponding pocket, as in the manner shown, the pockets and the nozzles intakes preferably being progressively increased in diametrical proportion from the front to the rear hinged of the nozzle carrier, and each nozzle having its intake formed so as to be slightly less in diameter than the diameter of the pocket in which it vibrates. During the vi bratory action of the nozzles, the lubricant is projected upwardly for its use as such upon the bearing surfaces between the journal and the bearing, and this oil may not only be stored in the pockets 1. but may also be present in the lower part of the oil chamher and below the line of the nozzle outlets. The oil as it is gradually consumed, drains down the inclined faces 29 of the base wall toward the. pockets, thus affording economy in the use of oil and the efficient use of a minimum quantity of the same, as will be readily apparent. The plate or bar l.O,-as already indicated, serves as a carrier for the nozzles 18 and acts under. the impulse of the journal cam-to impart vibratory movement to the nozzles relatively of the bases of their respective pockets, and thereby pro ect upwardly to the ournal the oil collected inflthese pockets. ()bviously the bearings of the roller and the spring 13 are capable of being retained under constant lubrication. From the foregoing, the essential features and elements of the device, together with its simplicity and other advantages thereof, will be readily apparent to those skilled in the art.

What we claim is:

1'. T he combination with a journal box and its journal, of a plurality of oil pockets below the journal, an oil projecting device for each-pocket, and a pivoted support for the projecting devices, the pockets and the oil intakes farther removed from the pivot being of lesser size than those which are closer.

2. The combination with a journal box and its journal, of a plurality of oil receiving pockets formed in the base of said box,

a nozzle carrier movably mounted in said box, and Oll projectlng nozzles for sald ournal xtending through said carrier toward said pockets.

The combination with a journal lOOX and its journal, of a plurality of oil collecting'pockets in said box, a nozzle carrier yieldingly mounted in said box and spaced away from aid pockets oil projecting nozzles extending through the body portion of said carrier toward the journal and toward and into said oil collecting pockets, and means operative during journal rotation for actuating said carrier.

4:. The combination with journal box and its journal, and its oil storage chamber, of plurality of separate oil containing pockets formed in the base wall of said niamber, said base wall downwardly inclined toward said pocket-s, an oil projectng nozzle-like device for each of said pockets, a support for said devices hingedly mounted near one end thereof and provided near its other end with a compression spring tending to force it upwardly toward the journal and with an anti-friction member,

a cam on said journal positively engaging' said member to depress the support against the s as the journal rotates, said do vices having restricted outlets directed toward the journal and provided with relatively larger intakes penetrating said pockets.

. in a device of the character described, the combination with an axle of a vibratory body member formed with an aperture, and a nozzle therefor adapted to project an oil stream against the under side of the axle, said nozzle having an outlet neck portion positioned and locked in said aperture and provided with an enlarged flared intake p01 tion depending below the lower face of the body member.
